Why did nature create woman? It seemed like a strange question. Of course, a woman is needed in order to help a man in matters of the soul, support him, feed him, raise children. But in fact, the main purpose of a woman in nature is to bear and give birth to a child. This is the peculiarity of the female reproductive system. Every cell in her body works so that she can reproduce her own kind.
The female reproductive system
The reproductive system of a woman is powered by the ovaries and uterus. It is worth understanding what happens in the ovaries, and what part the uterus takes in this process. An egg matures in the ovaries, which is then released into the abdominal cavity. In the uterus, under the influence of sex hormones, changes occur in the endometrium so that the fetal egg can be fixed in it after conception.
You need to understand that eggs, unlike male sperm, are a limited number. Even in the womb, the girl matures 400-450eggs that will exist until the end of reproductive age. By the way, about him. The reproductive age of a woman begins at 15-18 years and ends at about 40-50 years, each woman is different. Then comes menopause, when hormones are produced to a lesser extent.
The menstrual cycle and menstruation are terms you need to know in order to be able to calculate your period, understand how conception occurs, and so on.
Menstruation and the menstrual cycle: what's the difference?
So the first term to deal with is the menstrual cycle. This is a rather complex process in a woman, which is characterized by cyclic changes in the reproductive, endocrine, and nervous systems.
Menstruation is the discharge of blood from the genital tract, caused by the rejection of an unfertilized egg and the lining of the uterus. Usually, a girl's first menstruation begins at 10-12 years old.
So, now it is clear that these two words mean different processes, and not vice versa, as many people think. In simpler terms, the menstrual cycle is the time from the start of one period to the start of discharge the next month. But I must say that the cycle includes several stages, knowing which, it is easy to understand how to correctly calculate the monthly.
1 phase is the period of time from the first day of the appearance of blood to the moment of ovulation, that is, the release of the egg into the body cavity. This action occurs under the influence of the female hormone estrogen. The phase is called follicular.
2 phase - luteal, stage fromthe release of the egg until the next menstruation. The hormone of pregnancy, progesterone, joins the action of the main hormone.
Thus, if conception occurs during the period of ovulation, then the action of the main hormone slows down and is replaced by a second one. And if there was no conception, then the upper layer of the endometrium, along with the egg, is rejected, and menstruation occurs.
The length of the menstrual cycle. Norm. Pathology
Now you need to figure out what is the normal length of the menstrual cycle, why it is so, and what are the deviations from the norm.
So, the normal menstrual cycle lasts about 28 days for most women and girls, but it also happens that the interval between periods reaches 35 days or 21. These numbers are again explained by female physiology. The first phase of the cycle is aimed at ensuring that the egg matures and ovulation occurs, the second phase is aimed at changing the endometrium if conception occurs. If the fertilization of the egg does not take place, the functional layer of the endometrium departs, and after some time menstruation occurs.
Why don't my periods come on time?
If menstruation does not come on days 36-39, and the possibility of pregnancy is excluded, you should think about the woman's he alth. The absence of menstruation can be caused by many diseases of the female reproductive system, hormonal changes. The delay can be caused by oral contraceptives, as well as the usual stress or cold in our time, polycystic ovaries. If after 7-8 days your cycle does not return to normal, you need tovisit a doctor to find out the reasons why there is no period.
In order for the discharge to be regular and to have the opportunity to conceive a child, a woman needs to take vitamins, especially those containing lutein, eat right, be less nervous at work. After all, you must admit that he alth is more important, especially if you want to become a mother of a beautiful and he althy baby.
How do I know when my next period is due?
After reading the above, the question may arise: "How to calculate the period of menstruation?" In fact, there is nothing complicated about this. You will need attentiveness, a good memory, a sheet of paper or a calendar, a red pen and a desire to know when the next time to expect a period. In order to draw up a schedule of menstruation, calculate their duration, you need to know the date when the discharge began, and the day when they ended. It is best to mark them on a calendar or write them down in a notebook. In her notebook, a girl should note the duration of her period, her feelings at the same time, without forgetting anything, otherwise the calculation will be incorrect.
For the busiest, there are special programs on the phone that can be password-protected and used every month. At the same time, they will remind you of the next menstruation with a special signal or a pop-up window.
How to make a period calendar?
It has already been said that in order to calculate your period, you need a calendar. It's better if it's bigsize. Then it is more convenient to note the intensity of blood secretions. According to gynecologists, this will help you determine the pain of menstruation, because if it is accompanied by severe pain, it would be advisable to check your he alth.
So, the girl has the first day of her period, the discharge is smearing and not causing inconvenience. She should take her calendar, which is designed specifically for this, and circle this day with a red pen, and sign below with what intensity the blood is flowing and whether there is pain. If a small calendar is used, you need to shorten the word to one letter, that is, if menstruation is spotting and painless, then you can write it like this: “B and M”. So it is celebrated every day until the last and a characteristic is given to each. Allocations can be plentiful, insignificant, average and, as already mentioned, smearing.
The last day of my period has passed. Now you can live in peace for a month. The girl continues to celebrate her period next month every day, until the last one.
When data for two months appeared, it is possible to determine on which day ovulation will occur. To do this, subtract 14 from the last day of the cycle. Around this time, the egg will come out of the ovary, and it is quite possible that conception will occur.
Why do I need to know my next period?
Now that we know how to calculate the next period, the question arises - why? Why do you need to know the date of your period? There are several reasons, from very comical to quite serious.
So, if a female representative can calculate her period, she won't have to run to the store on the day the discharge starts and buy pads to ensure personal hygiene. She will already have a few necessary things for this period in her purse. Another comical reason is that a young man or husband will know when to agree with his beloved in everything and smile, even if he doesn’t like something, or quietly go to the TV so as not to annoy her. Then there are more serious reasons: a longer menstrual cycle may indicate ovarian dysfunction, which delays ovulation. Also, a delay or too short interval between periods can indicate serious illness and the inability to get pregnant.
Calendar method as a remedy for unwanted pregnancy
Above we talked about how to calculate your period in order to increase your chances of having a baby. But in life there are situations when a girl is still too young to have children, so she uses the calendar method to prevent pregnancy. This method is quite simple. During ovulation and 3 days after it, sexual intercourse is excluded. But, as already mentioned, the menstrual cycle tends to shift under the influence of various factors, so this method will not give a 100% guarantee of results.
But if a girl prefers this method, her period calculator will help her. It can be used to calculate both ovulation and the days when sex will besafe.
